The robotic arm opened its flexible claws and grabbed a large plate, precisely making it parallel to Wu Zong's arm bone, while the other robotic arm pinched the receiving plate extending from the plate, and slowly attached it to Wu Zong's joint tissue, and the tiny barb hooked his tissue muscles.

A tingling pain came, making Wu Zong grin, he didn't expect this thing to hurt so much, the barb pierced into his muscle tissue and made him feel like someone was picking at his nerves with many needles.

"Shall I continue?" Echo asked.

Zhang Yi looked at Wu Zong, saw Wu Zongchao nodded to himself, and said, "Go on." ”

For half an hour, when the last screw was fixed, Wu Zong was already sweating profusely, but fortunately, this torture finally ended.

Four robotic arms grabbed Wu Zong's brand-new robotic left arm.

"Try to move your fingers. Zhang Yi clenched his fists and stared nervously at the palm of the mechanical prosthetic.

Call.

Wu Zong took a deep breath and tried to slowly hook his fingers.

I only heard a slight sound of mechanical joint movement, and the index finger of the mechanical prosthetic slowly hooked up!

"Yes!" Zhang Yi cheered, his fists swung hard and he almost jumped up, looking at Wu Zong excitedly: "It's successful!

Wu Zong sighed again after his personal experience at Zhang Yi's amazing technique, that's right, this mechanical prosthetic has not had the slightest delay, except that it has no sense of touch, it is exactly the same as his own hand!

Wu Zong's excitement at this time was also beyond words, he needed to move his arm too much.

"Let it go, Echo. Wu Zong calmed down his excitement and said to Echo.

As the mechanical arm slowly withdrew, Wu Zong's left arm gradually strengthened, and finally, the last lifting mechanical arm was also withdrawn, and Wu Zong and Zhang Yi looked straight at the mechanical prosthetic with expectant eyes.

While!

With the sound of metal colliding, the mechanical prosthetic fell down in an instant like a chandelier with a broken thread!

Fortunately, Echo reacted extremely quickly and grabbed Wu Zong's hanging prosthetic leg with his mechanical arm, so that the heavy prosthetic leg did not tear off Wu Zong's arm.

Wu Zong couldn't control the prosthetic leg.

Zhang Yi's heart seemed to fall to the bottom in an instant.

Failed?

The two men looked at each other, and both found an incredible loss on each other's faces.

"No," Zhang Yi was the first to reflect, shaking his head and walking towards Wu Zong: "If you fail, you will never be able to hook your fingers." ”

As he spoke, he walked to Wu Zong's left and lifted his mechanical prosthetic, only to see the dry bones inserted in the mechanical prosthetics, like a child stealing the adult's rain boots, and the thin bones inserted in the prosthetic leg looked very pitiful.

"Hey!" Zhang Yi patted his head one by one.

"What's wrong," Wu Zong couldn't help but ask when he saw that Zhang Yi seemed to understand.

"You don't have musculature, so the frame of this prosthetic is too big for you," Zhang Yi understood the reason, and was a little annoyed that he hadn't noticed such an obvious problem: "It's like a person wearing a shoe that is several sizes bigger." ”

Immediately afterwards, Zhang Yi shook his head and put his mind at ease: "This is not difficult to solve. ”

Hearing Zhang Yi say this, Wu Zong also relieved his heart.

But then, Wu Zong saw a look of embarrassment on Zhang Yi's face, and couldn't help but ask again, "What's the matter?" ”

I saw Zhang Yi hesitate for a moment, and then laughed a little embarrassedly: "Hehe, uh, it's just that I have to remove it and install it when I change it." ”

Thinking of the heart-piercing pain, Wu Zong looked at Zhang Yi with a sneering face, and squeezed out five words from between his teeth: "Zhang Yi, your uncle!"

As Zhang Yi sent Wu Zong out of the studio in a huff, Zhang Yi never came out of the studio again for a whole night.

After Wu Zong came out of the studio, he went to find Li Bing and his party, and told them their own arrangements, Li Bing and the others knew that they would go to the zombie-dense city with Wu Zong after hearing this, and it seemed that they could not help him except to drag him down, and Wu Zong said that no matter whether it was successful or not, he would come back in half a month at most, so several people readily agreed.

As he spoke, Wu Zong suddenly thought that Zhang Yi said that there were only five people here now, but Wu Zong didn't seem to have seen the other three people except Zhang Yi and Wang Yue, who was a little wooden, so it was reasonable for them to borrow here and not say hello, so he took this opportunity to say hello to the other three under the leadership of Wang Yue.

One is that in addition to his appearance, which is different from Wang Yue, the temperament of the whole person, even including the plaid shirt, is almost like an engineering man carved out of a mold, named Li Qinghe.

One is a little girl with a pair of double ponytails, who looks younger than all of them, and is said to be Zhang Yi's little sister, and they all call her Lily.

There is another person who is more interesting, this person was originally in the monitoring room, and when he opened the door, Wu Zong's sharp wrist was about to come out. Because this man is so tall that his head can almost reach the door frame, and the whole person has a tiger's back, like a blind bear, and his name is probably related to his figure, and they all call him Big Bear.

But what's interesting is that although this person has a sideways face, he looks like he can fight very well, like a big brother in society, but in fact he is a good scientific researcher, and the wireless camera that attacked Wu Zong was transformed by him, and finally installed it by Zhang Yi, and they also made a bridge private network by themselves, which can almost cover the entire academy, and these things are also handled by him.

These people have their own characteristics, Wu Zong politely greeted a few people and urged Li Bing and the others to go back to the room to rest.

Wu Zong also went back to his room, he wanted to wait for Zhang Yi's mechanical arm to be changed and try it himself, but he couldn't wait until Wu Zong waited, the sound insulation here was very good, lying in the room was silent, he was too tired, he hung a glass on the doorknob, and then wrapped himself and lay on the bed and slowly closed his eyes.

This sleep was too comfortable, and when Wu Zong opened his eyes again, the room was still the same as when he was asleep, with a faint light emitting from the small orange lamp.

In a trance, Wu Zong thought that he had only squinted for a while, but after looking at the time, he realized that it was already more than ten o'clock in the morning.

Because all the light transmission points on the entire fourth floor were blocked by Zhang Yi and them with various boards, the entire fourth floor needed lights to illuminate both day and night.

Wu Zong remembered that the girl named Lily he saw yesterday was a little wilted, and he couldn't help but feel relieved, people can't go without sunlight for a long time, otherwise it will cause great trouble to the mental state of the whole person and the hormonal balance of the body, think about the time these people have been here for a long time, until yesterday, when they went to greet people, they could still shake hands with them politely, which is enough to show that the pressure resistance level of these people is already very good.

Just as Wu Zong wanted to go out to see the situation on Zhang Yi's side, the door of the room suddenly rang, and then Zhang Yi's voice rang out from outside the door: "Wu Zong?"

Wu Zong jumped up from the bed, walked quickly to the door, opened the door, and immediately saw Zhang Yi, whose eyes were full of bloodshots, standing in front of him with a tired face.

Looking at Zhang Yi's appearance, Wu Zong knew that Zhang Yi had not slept all night.

"OK," Zhang Yi raised his hand and motioned for Wu Zong to go to the studio with him.

Wu Zong wanted to open his mouth to care about Zhang Yi, but he really didn't care about others, so he simply patted Zhang Yi's shoulder, and the two walked to the studio.

With the heavy door opening again, Wu Zong re-entered the studio, which is full of industrial punk and modern cutting-edge technology.

He saw various parts scattered on the ground, and he could see that these parts should belong to many mechanical prosthetics, and it seemed that Zhang Yi had not only made one or two mechanical arms.

"You are a mechanical prosthetic that is the leader of hundreds of families and has been loved by thousands of people," Zhang Yi was tired, but it could be seen that he was very happy that his mechanical prosthetic could finally be used.

Then, he took out a mechanical prosthetic, Zhang Yi seemed to have sprayed it with spray paint, the whole mechanical prosthetic was pure black, glowing with a black luster, and on the top of the arm, Zhang Yi even spelled out three letters with silver-white aluminum sheets - M.E.C-1

"It's really quite angry," Wu Zong took the mechanical prosthetic leg and looked at the letters on it: "What does this mean." ”

"Abbreviation for Mechanic, Mechanic One. Zhang Yi raised his eyebrows, looking very proud of his work.

"Concise, good name" Wu Zong nodded, and then shouted: "Echo?"

"I'm here," the Echo seems to be on standby twenty-four hours a day, after all, it doesn't have to sleep.

"Can you calculate the approximate success rate this time," Wu Zong said as he took his mechanical prosthetic leg and stood on the iron plate in the middle of the room.

"More than ninety-six percent. Echo replied decently.

"It's quite high," Wu Zong easily put the mechanical prosthetic on the ground, untied the bandage on his left arm, stood up straight, took a deep breath, and then nodded: "Let's start, Echo." ”

Echo controlled the robotic arm to install the robotic arm for Wu Zong in an orderly manner, probably because of yesterday's experience, this time the installation of Wu Zong did not feel as painful as yesterday.

And this installation was unexpectedly fast, it didn't take almost twenty minutes, and the entire installation was completed, Wu Zong knew that this was the result of Echo's self-learning ability.

With a 'squeak', the last small screw on the little finger was also installed, with yesterday's experience, Echo did not put down the mechanical arm, but first carried Wu Zong's prosthetic leg like this, and a peaceful female voice came out of the speaker again: "The installation is complete, Mr. Wu Zong, if you are ready, please start the test." ”

Wu Zong pursed his lips and turned his head to look at Zhang Yi, who also stared at Wu Zong with a pair of bloodshot eyes and nodded to him.

Whew.

With a slight sound of mechanical turning, the five fingers of the prosthetic limb clenched into a fist, and then released again, Wu Zong repeated this action twice, and when he saw that there was no problem, he took a deep breath.

Then, his left big arm exerted force, and at the same time tried to retract his wrist, and with another soft sound, Wu Zong finally successfully lifted the prosthetic arm this time!

Wu Zong was so excited that he almost jumped up, twisting his reborn steel left hand with excitement and curiosity like a little boy who had just gotten a Transformers toy.

"It's done," Wu Zong muttered as he stared at the machine's left hand, "Zhang Yi, Echo, you made it." ”

"No," Zhang Yi shook his head and walked up and put his arms around Wu Zong's neck.

He and Echo said in unison, "We made it!"

"Hahaha, it worked!"

The two of them couldn't hold back their excitement anymore and laughed, jumping up on the steel plate like two children.

Wu Zong hadn't been so happy for a long time, he laughed insolently, waving his mechanical left hand to vent his emotions with Zhang Yi.

After a long time, Zhang Yi took the lead in jumping and couldn't move, sitting on the iron plate stupidly.

"Thank you," Wu Zong said to Zhang Yi sincerely.

"Thank me for what," Zhang Yi raised his eyebrows as he sat on the iron plate.

Zhang Yi's question made Wu Zong stunned: "Thank you for letting me use my left hand again." ”

I saw Zhang Yi grinning and said mysteriously: "If you just ask you to raise your left hand, then I don't need to dismantle so many mechanical arms." ”

Then, he stood up and flicked Wu Zong's mechanical left arm, making a crisp metallic sound.

"If yesterday's robotic arm was a loaf, then MEC1 was a hamburger," he winked at Wu Zong, "I added a lot of ingredients to it." ”
